Office 365 and Exchange 2010 mailboxes

[WhizInTraining]

Hi,

 

Down to my inexperience in IT, I appear to have got into a bit of a sticky situation, and was wondering if you guys knew a way around it.

 

We had a number of our students who couldn't access their mailboxes, and, after enabling one, it worked, so my logic (I know, it's stupid now) was to Enable all, so that they were all working... Or so I thought.

 

We now have students receiving e-mails on both the Office 365, AND through the on premises exchange.

 

Any ideas on how we can get around this, and get it so that the students are just in Office 365?

 

Thanks

Make sure you MX records are setup correctly and pointing to office365 (not your onsite exchange server)
